Side Effects: High doses may cause stomach discomfort, diarrhea, or vomiting. In rare cases, it has been linked to liver issues.

Ginseng
Ginseng, particularly Panax ginseng, is widely used for its potential to enhance brain function. It is believed to improve memory, focus, and reaction speed while reducing mental fatigue. Additionally, its antioxidant properties help protect brain cells from oxidative stress.
Ginseng contains anti-inflammatory compounds called ginsenosides, which have been studied for their neuroprotective effects. A 2018 review found that ginsenosides may reduce beta-amyloid levels in the brain4—proteins associated with Alzheimer's disease and cognitive decline. Lowering beta-amyloid accumulation could potentially help slow the progression of neurodegenerative conditions and support overall brain health.
Dosage Recommendations: 200 mg to 3 grams daily for up to 12 weeks.
Side Effects: Long-term use (beyond six months) may cause hormone-like effects. Common side effects include difficulty sleeping, while rare cases may experience severe rash, liver damage, or allergic reactions.
Curcumin
Curcumin is the active compound in turmeric, a spice commonly used in Indian cuisine. It is known for its anti-inflammatory and antioxidant properties, which may help protect the brain from damage associated with conditions like Alzheimer’s disease.
Studies suggest that curcumin can enhance working memory, improve mood and attention, and reduce fatigue. Research has also linked curcumin supplementation to lower levels of brain plaques in regions associated with memory and cognitive function, a key factor in Alzheimer’s progression.5
Dosage Recommendations: Up to 1.5 grams daily for up to nine months.
Side Effects: Generally well-tolerated, but high doses may cause mild stomach upset, nausea, dizziness, or diarrhea.
L-theanine
L-theanine is a naturally occurring compound found primarily in green tea and certain other plants. It is known for its ability to enhance mental alertness, improve reaction time, and support memory.
A study involving 69 adults aged 50 to 69 found that a single 100.6 mg dose of L-theanine significantly improved reaction time and working memory.6
Additionally, L-theanine supplements may help reduce stress and promote a sense of calm and relaxation.
Dosage Recommendations: 100–200 mg per day. Consult a healthcare provider for personalized guidance.
Side Effects: Generally well-tolerated, but excessive intake may cause nausea, an upset stomach, or irritability.
Rhodiola Rosea
Rhodiola rosea is an adaptogenic herb known for its ability to help the body manage stress and combat brain fog. It may also reduce fatigue, anxiety, and depression, contributing to overall brain health.
Research suggests that Rhodiola can enhance memory, focus, and mental clarity, particularly in high-stress situations.7 It is often used by older adults seeking to maintain cognitive sharpness and improve learning ability.
Dosage Recommendations: 100–600 mg daily for up to 12 weeks.
Side Effects: May cause dizziness, dry mouth, or excessive saliva in some individuals.

Lion’s Mane Mushrooms
Lion's mane mushroom (Hericium erinaceus) has gained significant attention for its potential cognitive benefits. Research suggests that lion's mane mushroom for brain health may be particularly effective in supporting memory and overall cognitive function.
Studies indicate that lion’s mane mushroom and its extracts can help reduce memory loss in animal models. They may also protect against brain damage by preventing the buildup of amyloid-beta plaques, which are associated with Alzheimer’s disease.8
Dosage Recommendations: 500–1,000 mg daily, typically taken in capsule or powdered form.
Side Effects: Generally well-tolerated, but some individuals may experience mild stomach discomfort.
Gotu Kola
Gotu kola is a well-known herb in Ayurvedic and Chinese medicine, traditionally used to support memory and brain function. Often referred to as the "herb of longevity," it may help protect brain cells from damage, making it potentially beneficial for individuals with Alzheimer’s disease.
In addition to its neuroprotective properties, gotu kola is known for its anti-inflammatory effects and its ability to promote healing, particularly in blood vessels and arteries. Improved circulation may enhance blood flow to the brain, supporting cognitive function.
A 2021 review in Frontiers in Pharmacology suggested that gotu kola may reduce oxidative stress linked to Alzheimer’s disease and improve cognitive performance.9
Dosage Recommendations: 60–450 mg daily for 4 to 12 months.
Side Effects: May cause nausea or stomach pain in some individuals.
Best Practices for Using Supplements
To maximize the benefits of memory support supplements, follow these guidelines:
-
Start Slowly: Begin with a low dose to assess your body’s response, then gradually increase to the recommended amount.
